Add a Request Header to a REST Request

See more REST Examples

Demonstrates Rest.AddHeader, which adds an HTTP request header field. The 1st argument is the field name and the 2nd is the value. Adding a header whose name already exists replaces the previous value.

local chilkat = require("chilkat")

local rest = chilkat.Rest.new()

-- Connect to the REST server.  The 3rd argument enables TLS (use true for HTTPS on port 443),
-- and the 4th enables automatic reconnection if the connection is dropped between requests.
local bTls = true
local bAutoReconnect = true
local success = rest:connect("example.com", 443, bTls, bAutoReconnect)
if not success then
    print(rest.last_error_text)
    return
end

-- Add request header fields.  The 1st argument is the field name and the 2nd is the value.
-- Adding a header with a name that already exists replaces the previous value.
rest:add_header("Accept", "application/json")
rest:add_header("X-Custom-Header", "example-value")

local responseText = rest:full_request_no_body("GET", "/api/data")
if not rest.last_method_success then
    print(rest.last_error_text)
    return
end

print(responseText)
